How to grow:
The seeds of trumpet flower should be sown on the surface either before the last frost of spring or in the autumn. Incarvillea members like to grow in sunny area of the garden, and will not tolerate high humidity. Trumpet flowers have a preference for soils that are of a sandy nature, with a slightly acidic rich growth medium. 
If you prefer to first grow Trumpet flowers indoors then they should be started about two months before the expected last frost of spring. They will take about three to eight weeks to germinate at a temperature of 15 to 21 degrees Celsius. Once you have trumpet flower (Incarvillea) seedlings transplant them at 25cm (small species) to 50cm apart (large).
